The Woman and the Dragon

A detective thriller set a hundred years in the future, in an era many believed to be humanity's golden age.
People had eliminated all causes of strife and conflict, becoming true humanists. Everyone was of one sex, one race, and one nation. Justice was administered by a seemingly infallible artificial intelligence. It seemed that humanity had finally reached the end of history, where nothing dramatic could ever happen again.
But then a theft occurred, setting off an avalanche of terrifying events that left many dead and the world on the brink of collapse.
